File: lib/encryptor.rb line 57
By danpal:

Hm, the key here is really just a secret, not really a key in the cryptography sense. An example is :key => "secret". this would be translated as:

+ cipher.key = OpenSSL::PKCS5.pbkdf2_hmac_sha1("secret", "unique_salt", 2000, cipher.key_len)

The reason to use the name :key is such that encryptor was already using key.
But please explain further if I messed up something...I didn't fully understood you.
